Research ArticleOpen accessAll words, across the recordHydraulic Flow through Engineering Bentonite-Based Containment BarriersEric Wooi Kee Loh, Devapriya Chitral WijeyesekeraThis paper presents the use of software modelling as a tool to study the impact of hydraulic "resistivity" on the contaminant transport through bentonite-based containment barriers. A sensitivity analysis on the predicted data was carried out by varying the boundary conditions as well as the hydraulic resistance to flow through varying contaminant transport parameters. Accordingly, both advective and diffusive flow … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 4 Nov 2015 · 6,703 accessesView PDF Cite
